GAS-HEATER FOR FURNACES.

Application filed September 17, 1913.

To all whom it may concern:

Be it known that I, FELIX KORN, a citizen of the United States, and aresident of F anwood, in the county of Union and State of New Jersey,have invented a new and Improved Gas-Heater for Furnaces, of which thefollowing is a full, clear, and exact description.

Among the principal objects which the present invention has in view are:to provide a heater adapted to heat the water in a jacket surroundingthe fire space of a boiler; to provide a heater and means forcontrolling the same to maintain at relatively small gas expenditure theinitial heat produced by the heater; to provide means for more fullygraduating the heat maintained in the fire space of a boiler; and toprovide ring heaters having means for introducing the fuel at oppositeends thereof.

In the drawings, Figure 1 is a pictorial view showing in front elevationand in light lines a boiler of conventional type, and in heavy lines aheater constructed and arranged in conformity with the present inventionapplied thereto; Fig. 2 is a side elevation of the heater and partsconnected therewith, the heater being shown as separated from theboiler; Fig. 3 is a top plan view of the heater shown in Fig. 2.

To equip the boiler, such as the conventional boiler 8 shown in Fig. 1,the grate bars with which said boiler is usually provided, are omittedor removed. A pedestal 9 is mounted within the shell of the boiler 8.The pedestal 9 is provided to support the base 10 of a burner having aseries of pipes or tubes 11 extending therefrom to spread the flame areaof the burner. The burner having the base 10 and tubes 11 is ofconventional form and construction. The base 10 has interiorcompartments, each of which is supplied by one of the feed pipes 12, 13and 14.

In arranging my heater in the fire-space of a furnace or boiler, care isexercised that the base 10 rests in approximately the same plane as thatusually occupied by the grate bars of the conventional boiler, whichhave been either removed or omitted.

The pipes 12, 13 and 14.- are supplied with Specification of LettersPatent.

gas from the lower supply main 15. The flow of gas into said feed pipesis regulated by manipulating cocks 16 17 and 18, respectively.

Circumvallating the tubes 11 and disposed in a horizontal planesubstantially coincident with the outermost of said tubes s the lowerring 19. Said ring is disposed in the fire-box below the upper ring 20.The rings 19 and 20 are substantially equal in diameter, and each has aseries of perforations 21 and 22, respectively, formed therein and inthe outer wall thereof, as best seen in Fig. 2 of the drawings. Theupper ring 20 is also provided with a number of scattered perforations23 disposed at substantially the crown of said ring. The two rings areemployed by me to maintain the heat in the body of the water in thewater-jacket 0r shell of the furnace 8, after the same has been raisedto any desired temperature by the operation of the full force of theburner herein described. The crown of the fire-box with which thefurnace is provided crosses above the ring 20, therefore, the flameemitted by the perforations 23 impinges or afl'ects directly the wall ofthe crown and the water in the jacket carried thereabove. Ascircumdistinguished from the ring 20, the ring 19 has a single line ofperforations 21, the flames emitted therefrom spreading in a horizontalplane toward the side wall of the jacket or shell of the furnace orboiler. The flame thus emitted from both the ring 19 and the ring 20 isdeflected just before reaching the wall of the jacket, by the draft ofair passing upward from the fire-box. Therefore, the wall is saved fromthe effect of the direct impact of the flame.

The rings 19 and 20 are similar in construction, in that each is openat' both ends to receive a supply of fuel from distinct branchfeed-pipes. By thus feeding the fuel into both ends of the perforatedpipe or rings, the supply and consequent heat are maintained more evenlyover the complete circles formed by said rings. Also, by thus feedingthe gas, it will be found that the regulation of the heat or flamewithin said rings may be more nicely adjusted to the conditions underwhich the heating plant is operated.

The lower ring 19 is supplied with fuel through the branch pipes 2a and25. The pipes 2% and 25 are supplied by cocks 26 and 27, from the branchpipe 28. The branch pipe 28 is dropped below and openly connected withthe main 15 and with a loop pipe 29. The loop pipe connects the main 15with a main 30, which supplies the fuel to the ring 20 through cocks 31and 32 and branch pipes 33 and 341-.

As will be seen best in Fig. 1 of the drawings, the mains 15 and 30 areboth connected with a supply pipe 35. The flow of the gas through themains 15 and 30 is con trolled by manipulating cocks 36 and 37. It willbe observed that approximately the same arrangement of feeding the gasor fuel from both ends of a circuit, from a common supply, is followedin the mains 15 and 30 and loop pipe 29 as outlined with reference tothe rings 19 and 20. The result of this construction and arrangement ofthe mains and loop pipe is similar to that noted as appertaining to saidrings.

It will be understood that all the cocks above described except thosedesignated by the numerals 36 and 37 have air-mixing chambers 38,whereby the air and gas forming the burning fuel employed in connectionwith this heater, are mixed.

When a furnace is equipped with a burner constructed and arranged asabove described, and as shown in the accompanying drawings, theoperation is simplified, in that all that is necessary in starting afire is to light one of the burners, preferably the upper ring 20. Whenthe flame has been es tablished in the upper ring 20, the gas may beturned on by the cocks controlling the flow into the base 10, to enterthe chamber through the tubes 11; the gas coming in contact with theflame in the ring 20 would ignite. Likewise, the fuel delivered into thering 19 would ignite to establish the jets emitted from the perforations21 therein.

The heater comprising the base 10 and the distributing tubes thereof,the ring 19 with the flames extending laterally therefrom, and the ring20 with the jets extending 'both laterally and vertically therefrom, hasa capacity preferably in excess of that required for the usual service,whereby the radiating medium-water or steammay be initially quicklyheated. After the heat has been raised, the burner capacity may bereduced by manipulating the cooks 16, 17 and 18, to gradually cut outthe burner having the base 10, and thereafter maintain the heat in theradiating medium with heat generated by means of the rings 19 and 20.The heat deliver (1 from said rings is most efficient, the fia 18S beingdirected so as to sweep the inner wall of the fire box, water-jacket, orshell of the boiler 8.

Should it be desired to still further reduce the heat, this is bestaccomplished by either reducing the force in the ring 19, ordiscontinuing its use entirely. It will be noted that by diminishing theflow of gas into said ring, at either end thereof, the residual pressureis nicely adjusted to diminish the resultant consumption. Ifdiscontinued entirely, the heat is maintained by the flame emitted fromthe ring 20.
